I have never heard of an electric bicycle, folding or otherwise. My question is why would you want an electric bicycle since that would defeat the purpose of getting excercise by riding the bicycle ? Ironicly, it has been a combination of our collective laziness and our desire to always be first that has led to the popularity of the automobile. It wouldnt hurt us to go back to bicycles and/or our feet for general transportation.

I am just shocked you can actually fold an electric bicycle- I need to get one- probably save me lots on transportation expenses.

Why not just buy a regular fold up bike. It'll save energy (eletrically) and is more enivironmentally friendly, especially if you're going on a bus or train anyway.
